"Using geochronology and volumes of volcanic units,
they proposed probabilistic assessments of future
volcanic eruptions and suggested that a fourth
caldera-forming eruption was the least likely
scenario. Instead, they suggested that intracaldera
rhyolitic eruptions and small basaltic or rhyolitic
extra-caldera eruptions were more likely..."
